2 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
3 some Microsoft software would not correctly recognize data in the
6 Made some small improvements to the compression algorithms:
7 LZX compression ratio was slightly improved.
8 XPRESS compression ratio and speed was slightly improved.
9 LZMS compression speed was slightly improved.
11 Improved handling of WIM XML data. wimlib no longer drops unrecognized
12 elements when exporting images. In addition, two API functions were
13 added for better access to elements in the XML document:
14 wimlib_get_image_property() and wimlib_set_image_property().
16 Added support for (unsafe) in-place compaction of WIM files.
18 Improved performance of image export by reusing metadata resources
19 instead of always rebuilding and recompressing them.
21 Improved performance of wimlib_update_image() by delaying the update to
22 the WIM's XML document until a write is requested.
24 On Windows, the target of an extraction may now be a reparse point
25 (which will be dereferenced).
27 On Windows, wimlib now correctly restores non-Microsoft reparse points.
28 However, this remains broken in NTFS-3g mode due to a libntfs-3g bug.
30 On Windows, wimlib now has improved performance when archiving files
31 from a filesystem backed by a WIM (a "WIMBoot" setup).
33 Several improvements to System Compression (compact mode) support:
35 wof.sys (or wofadk.sys) is now automatically attached to the
36 target volume if needed.
38 Compact-mode extractions now work correctly with wofadk.sys on
39 older versions of Windows.
41 For compatibility with the Windows bootloader, the requested
42 compression format now is overridden on certain files.
47 This release primarily contains various minor bug fixes and
48 improvements, including:
50 Improved handling of deep directory structures.
52 Fixed a bug where on 32-bit systems, the library could enter an
53 infinite loop if a WIM file was malformed in a specific way.
55 Added a workaround for a case where libntfs-3g may report
56 duplicate streams in an NTFS file.
58 Windows symbolic links and junctions in mounted WIM images are
59 now automatically rewritten to be valid in the mounted location.
61 Reparse point fixes: correctly handle the "ReparseReserved"
62 field, and correctly handle "empty" (data-less) reparse points.
64 On Windows, wimlib now acquires SeManageVolumePrivilege, which
65 is needed to create externally backed files using the
68 Improved validation of filenames.
70 Improved LZMS decompression speed.
72 The configure script now honors alternate pkg-config settings.
74 Links have been updated to point to the new website.
76 In addition, experimental support has been added for compressing
77 extracted files using System Compression on Windows 10. This
78 functionality is available through the new '--compact' option to
79 'wimapply' and 'wimextract' as well as new library flags.
82 Fixed a bug in the LZX decompressor: malicious input data could cause
83 out of bounds writes to memory (since wimlib v1.2.2).
85 The output of the 'wiminfo' command now consolidates various boolean
86 flags (such as "Relative path junction") into a single line.
88 A file can now have both an unnamed data stream ("file contents") and a
89 reparse point stream. Such files can exist as a result of the use of
90 certain Windows features, such as offline storage, including "OneDrive".
91 wimlib will now store and restore both streams on Windows as well as in
92 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
94 On Windows, named data streams of encrypted files are no longer stored
95 twice in WIM archives.
97 On Windows, named data streams are now correctly extracted to existing
98 "readonly" directories. Before, an error would be reported.
100 On Windows, it is now possible to do a "WIMBoot mode" extraction with
101 non-standalone WIMs such as delta WIMs.
103 On Windows, when doing an extraction in "WIMBoot mode", files larger
104 than 4 gigabytes are now never extracted as externally backed. This
105 works around a bug in Microsoft's "WOF" driver.
107 The '--enable-verify-compression' configure option has been removed. If
108 you want to verify a WIM file, use the 'wimverify' program.
110 The way the "file count", "directory count", "total bytes", and "hard
111 link bytes" image statistics (stored in the WIM XML data) is calculated
112 has been slightly changed.
114 In mounted WIM images, the disk usage provided for each file (st_blocks)
115 is now the compressed size rather than the uncompressed size.
117 The performance of the NTFS-3g and Windows capture modes has been
120 On UNIX-like systems, symbolic links whose targets contain the backslash
121 character are now handled correctly (losslessly).
124 Improved the LZX compressor. It is now 15-20% faster than before and
125 provides a slightly better compression ratio.
127 Improved the LZMS compressor. It now provides a compression ratio
128 slightly better than WIMGAPI while still being faster and using slightly
131 The compression chunk size in solid resources, e.g. when capturing or
132 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
133 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
134 better compression ratio and is the same value that WIMGAPI uses. The
135 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
136 lower than WIMGAPI's memory usage, but if it is too much, it is still
137 possible to choose a lower value, e.g. with the '--solid-chunk-size'
138 option to wimlib-imagex.
140 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
141 accept the 'K', 'M', and 'G' suffixes.
143 Files are now sorted by name extension when creating a solid WIM file.
145 Fixed various issues related to capture/apply of EFS-encrypted files on
148 The file list printed by 'wimdir' is now sorted by the platform-specific
149 case sensitivity setting, rather than always case sensitively. This
150 also affects the library function wimlib_iterate_dir_tree().
152 On Windows, some error and warning messages have been improved.
155 The Windows binary distribution no longer contains third party DLLs.
156 These dependencies are instead compiled directly into the libwim DLL.
158 Added more fixes for wimlib on non-x86 architectures such as ARM.
160 Extracting files to a Windows PE in-memory filesystem no longer fails if
161 the target files do not yet exist.
163 Improved the performance of XPRESS compression and LZMS decompression.
165 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
166 It will automatically be faster on newer Intel and AMD processors.
168 Removed the --with-imagex-progname and --enable-more-assertions
172 Fix for very slow export from solid WIM / ESD files.
174 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
176 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
177 may use this to treat some types of errors as non-fatal.
179 The library now permits making in-memory changes to a WIMStruct backed
180 by a read-only WIM file.
182 Fixes for "WIMBoot" extraction mode (Windows only):
184 When not using the WOF driver, extraction no longer fails if the
185 disk containing the WIM file has too many partitions.
187 When matching patterns in [PrepopulateList], all hard links of
188 each file are now considered.
190 The system registry files are now automatically treated as being
191 in [PrepopulateList].
193 Added a hack to try to work around an intermittent bug in
194 Microsoft's WOF (Windows Overlay Filesystem) driver.
197 Made more improvements to the XPRESS, LZX, and LZMS compressors.
199 A number of improvements to the Windows port:
201 Fixes for setting short filenames.
203 Faster "WIMBoot" extraction.
205 Updated and slimmed down the dependent DLLs.
207 ACL inheritence bits are now restored.
209 Mandatory integrity labels are now backed up and restored.
211 Added a workaround for an issue where in rare cases, wimlib could create
212 a compressed data stream that could not be read correctly by Windows
213 after an extraction in "WIMBoot" mode.
216 Added file count progress data for
217 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
218 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
220 Added support for testing file exclusions via the user-provided
223 Some documentation improvements.
225 Made some clarifications to the license text in the COPYING file.
228 Made more improvements to the XPRESS, LZX, and LZMS compressors.
230 The default compression mode for wimcapture is now LZX compression in
231 its default mode, which is the same as '--compress=maximum'.
233 You can now specify an optional integer compression level to the
234 '--compress' option; e.g. '--compress=lzx:75'.
236 Made a minor change to the LZMS compressor and decompressor to fix an
237 incompatibility with the Microsoft implementation. In the unlikely
238 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
239 earlier and a checksum error is reported when extracting files from it
240 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
243 Added 'verify' subcommand to wimlib-imagex.
245 Notable library changes:
247 Custom compressor parameters have been removed from the library
248 in favor of the simpler level-based API.
250 Decompressor parameters have been removed entirely.
252 Library users can now specify a custom file for warning and
253 error messages to be sent to, rather than the default of
256 New progress messages:
257 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
258 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
260 New function: wimlib_verify_wim().
263 Improved compression, decompression, and extraction performance.
265 Improved compatibility with version 3584 WIM / ESD files:
266 - Add support for reading and writing multiple solid blocks per
267 archive, which WIMGAPI/DISM can create when appending an image.
268 - Correctly create solid blocks larger than 4 GiB.
270 'add' commands passed to wimupdate will now replace existing
271 nondirectory files by default. Use the --no-replace option to get the
274 The license for the library now contains an exception that allows using
275 it under the LGPL. See the COPYING file for details.
277 In reparse-point fixup mode (the default for capture), symbolic links
278 and junctions that point outside the tree being captured are no longer
279 excluded from capture.
281 Added support for "WIMBoot" capture and extraction. See the
282 documentation for the new '--wimboot' option to wimcapture and wimapply
283 for more information.
285 On UNIX-like systems, you can now backup and restore device nodes, named
286 pipes, and sockets. In addition, 32-bit user and group IDs are now
289 The way that UNIX data is stored in WIM files has been changed. If you
290 captured any WIMs with the --unix-data option, to upgrade them you'll
291 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
292 re-capture them with --unix-data using this version.
294 wimlib now understands tagged metadata items, such as object IDs, that
295 can be stored in WIM directory entries.
297 Removed the --hardlink and --symlink options to wimapply, since I don't
298 think they are too useful and they got in the way of improving the code.
300 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
302 The 'mkwinpeimg' script now supports writing the ISO image to standard
305 The <ARCH> element in WIM XML data is now exported correctly.
307 On Windows, sparse file attributes are no longer set on extracted files.
308 Oddly enough, this actually saves disk space in some cases.
310 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
311 supported. Mounting WIM images now always requires extended attribute
312 support. Use --without-fuse to disable support for mounting WIM images;
313 this will also disable the need for extended attribute support.
315 Configuring with --enable-ssse3-sha1 now works correctly.
317 The shared library version has been bumped up. The main
318 incompatibilities are:
320 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
321 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
324 - User-provided progress functions are now registered using a
325 separate function, wimlib_register_progress_function(). The
326 'progress_func' argument to many functions no longer exists.
328 - The return value from user-provided progress functions is now
331 - A context argument has been added to the prototype of
332 user-provided progress functions.
334 - 'struct wimlib_capture_config' has been removed. The library
335 now takes the path to the configuration file directly. This
336 affects wimlib_add_image(), wimlib_add_image_multisource(),
337 and wimlib_update_image(). However, a NULL value passed in
338 the argument retains the same meaning.
340 - Removed deprecated functions: some (de)compression functions,
341 wimlib_extract_files(), and wimlib_print_metadata().
343 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
344 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
345 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
347 - Removed some progress messages:
348 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
349 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
350 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
353 - Removed some error codes. Numbering stays the same.
355 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
356 WIMLIB_UNMOUNT_FLAG_FORCE.
358 - WIM paths passed to progress functions now have a leading
362 Case-insensitive comparisons of strings (e.g. filenames) containing
363 UTF-16 codepoints above 32767 are now done correctly.
365 Fixed build failure on Mac OS X.
367 wimunmount now provides the '--new-image' option to cause changes to a
368 read-write mounted image to be committed as a new image rather than as
369 an update of the mounted image. (The corresponding new library flag is
370 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
372 The LZMS ("recovery") compression chunk size, or "dictionary size", may
373 now be up to 1 GiB (1,073,741,824 bytes).
375 The performance of LZX ("maximum") and LZMS ("recovery") compression
376 with large chunk sizes has been slightly improved.
379 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
380 decompressed correctly.
382 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
383 occurred in an unlikely case, and due to validity checks it did not
384 affect successfully created archives.
386 Fixed a minor compatibility issue with the LZMS compressor and
387 decompressor. This is *not* the default compression type and was only
388 introduced in v1.6.0. In the unlikely event that you created an
389 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
390 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
393 Memory usage for LZMS and LZX compression has been decreased.
395 wimextract now allows wildcard characters in paths specified on the
396 command line. Also, the '--strict-wildcards' option has been removed
397 and replaced with the inverse option '--nullglob'. See the
398 documentation for wimextract for more details and changes.
400 The wimlib_extract_files() function is now considered deprecated in
401 favor of wimlib_extract_paths().
403 Fixed more permissions problems when extracting files on Windows.
405 A new '--no-attributes' option has been added to wimapply and
406 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
408 The default chunk size is now set correctly when changing the
409 compression type of a WIM, for example with 'wimoptimize'.
411 The '--metadata' option to wiminfo has been replaced with the
412 '--detailed' option to wimdir.
414 In relevant wimlib-imagex commands, '--solid' may now be used as an
415 alias for '--pack-streams'.
418 Support for extracting and updating the new version 3584 WIMs has been
419 added. These WIMs typically pack many streams ("files") together into a
420 single compressed resource, thereby saving space. This degrades the
421 performance of random access (such as that which occurs on a mounted
422 image), but optimizations have been implemented for extraction. These
423 new WIM files also typically use a new compression format (LZMS), which
424 is similar to LZMA and can offer a better compression ratio than LZX.
425 These new WIM files can be created using `wimcapture' with
426 the '--compress=lzms --pack-streams' options. Note: this new WIM format
427 is used by the Windows 8 web downloader, but important segments of the
428 raw '.esd' files are encrypted, so wimlib will not be able to extract
429 such files until they are first decrypted.
431 wimlib now supports extracting files and directories from a WIM image
432 based on a "listfile" that itself contains the list of paths to extract.
433 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
434 and for the library itself, the new APIs are wimlib_extract_pathlist()
435 and wimlib_extract_paths(). Path globs containing wildcard characters
438 For searching WIM files, wimlib now has configurable case sensitivity.
439 The default on Windows is still case-insensitive and the default on
440 UNIX-like systems is still case-sensitive, but this can be overridden
441 on either platform through flags to wimlib_global_init(). For
442 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
443 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
446 Support for compression chunk sizes greater than the default of 32768
447 bytes has been added. A larger chunk size typically results in a better
448 compression ratio. However, the MS implementation is seemingly not
449 compatible with all chunk sizes, especially for LZX compression, so the
450 defaults remain unchanged, with the exception of the new LZMS-compressed
451 WIMs, which use a larger chunk size by default.
453 The compression/decompression API exported by wimlib has been changed.
454 Now one set of functions handles all supported compression formats.
456 `wimcapture' and `wimappend' will now display the progress of scanning
457 the directory tree to capture, in addition to the progress of writing
458 data to the WIM. The '--verbose' option no longer does anything. The
459 library API change for this is the addition of several members to
460 `struct wimlib_progress_info_scan' available to progress callbacks.
462 `mkwinpeimg' now correctly handles the '--start-script' option when the
463 start script is not in the working directory.
465 Sequential extraction, previously requested by using
466 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
467 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
468 behavior (extract in file order).
471 The new LZX compressor added in v1.5.2 has been improved and is now
472 enabled by default, except when `wimcapture' or `wimappend' is run
473 *without* the '--compress' option, in which case the faster LZX
474 compressor is used (the same as before). This behavior is reasonably
475 consistent with ImageX which actually uses "fast" (XPRESS) compression
476 by default. In those cases, use '--compress=maximum' to explicitly
477 capture a WIM image using the new (slower but better) LZX compressor.
479 The '--compress-slow' option still exists to `wimlib-imagex optimize',
480 but its new behavior is to tweak the new LZX compressor even more to
481 produce an even better compression ratio at the cost of more time spent
484 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
485 which recompresses the WIM file using the specified compression TYPE.
486 The new library API function used for this is
487 wimlib_set_output_compression_type().
489 Added the wimlib_get_xml_data() function to allow library clients to
490 easily retrieve the raw XML data from a WIM file if needed.
492 Fixed a bug that could cause an error code to be incorrectly returned
493 when writing XML data containing a <WINDOWS> element.
495 Mounted WIM images will now correctly show the default file stream even
496 if appears in the alternate data stream entries of the corresponding WIM
500 Added a new experimental LZX compressor which can be enabled by passing
501 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
502 optimize'. (The latter is only applicable if the WIM is already
503 LZX-compressed and the '--recompress' option is also given.) The
504 experimental compressor is much slower but compresses the data slightly
505 more --- currently usually to within a fraction of a percent of the
506 results from WIMGAPI/ImageX.
508 A workaround has been added for compatibility with versions of WinPE
509 that interpret alternate data stream entries in the boot WIM
512 An alignment bug that caused a crash in the LZX decompressor on some
515 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
516 the WIM header when restoring the previous state of a WIM it failed to
519 Added a workaround to avoid an access denied error on Windows when
520 replacing a WIM file that another process has opened.
523 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
524 needed to be handled.
526 A bug in the interpretation of negative IMAGE indices in the
527 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
528 `wimlib-imagex append' has been fixed.
530 A workaround has been added to successfully apply security descriptors
531 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
532 2013.1.13 or earlier.
534 `wimlib-imagex capture' can now accept the '--delta-from' option
538 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
539 to standard output and applying images from standard input, but they are
540 not compatible with Microsoft's software and are not created by default.
541 See the documentation for --pipable flag of `wimlib-imagex capture' for
544 To better support incremental backups, added support for declaring an
545 image as a modified form of another image. See the documentation for
546 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
549 Added supported for "delta" WIMs. See the documentation for the
550 '--delta-from' option of `wimlib-imagex capture'.
552 The library support for managing split WIMs has been changed to support
553 other arrangements, such as delta WIMs, and be easier to use. This
554 change is visible in `wimlib-imagex', which also can now accept the
555 '--ref' option multiple times, and also now supports "delta" WIMs as
558 wimlib now preserves WIM integrity tables by default, even if
559 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
560 behavior of `wimlib-imagex' whenever the WIM being operated on contains
561 an integrity table and the '--check' option is not specified.
563 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
564 (when --compress is not specified). This provides the best compression
565 ratio by default, which is usually what is desired, at a cost of some
568 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
569 is the command as in `wimlib-imagex COMMAND'; for example, it can be
570 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
571 appropriate hard links are created in UNIX installations of
572 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
573 batch files that emulate this behavior are generated.
575 Security descriptors are now extracted correctly on Windows.
577 Fixed archiving DOS names in NTFS-3g capture mode.
579 The extraction code has been rewritten and it will now be easier to
580 support new features on all supported backends (currently Win32, UNIX,
581 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
582 now supported on all backends, not just UNIX.
584 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
585 than the WAIK itself.
587 wimlib_global_init() now, by default, attempts to acquire additional
588 privileges on Windows, so library clients need not do this.
590 This update bumps the shared library version number up to 9, since it is
591 not binary compatibible with previous releases.
594 Fixed bug in `wimlib-imagex export' that made it impossible to export an
595 image from a WIM that is readonly at the filesystem level.
597 Return error code rather than segfaulting when trying to list files from
598 a non-first part of a split WIM.
600 Joining a WIM will now preserve the RP_FIX and READONLY flags.
603 On Windows, paths given to wimlib-imagex are now treated case
606 Improved behavior regarding invalid filenames; in particular, on
607 Windows, wimlib-imagex will, when extracting, now omit (with an option
608 to override this default) filenames differing only in case, or filenames
609 containing characters not valid on Windows.
611 On Windows, wimlib now supports capturing and extracting long paths
612 (longer than the so-called MAX_PATH).
614 On Windows, `wimlib-imagex update' now acquires proper privileges when
615 running as an Administrator.
617 `wimlib-imagex update' will now complain if no image is specified when
618 trying to update a multi-image WIM.
620 `wimlib-imagex update' now supports specifying a single update command
621 directly on the command line using the --command option.
623 wimlib-imagex will now choose different units for progress messages,
624 depending on the amount of data that needs to be processed.
626 `wimlib-imagex append' will now generate a unique WIM image name if no
627 name is specified and the defaulted name already exists in the WIM.
629 wimlib now allows you to create unnamed WIM images, which can then only
630 be referred to by index.
632 wimlib now allows you to explicitly declare you want write access to a
633 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
636 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
639 Progress callbacks have been added to wimlib's wimlib_update_image()
642 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
643 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
646 NTFS-3g capture now only warns about two conditions previously treated
649 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
652 wimlib now correctly detects and returns an error when reading a WIM
653 image with a cyclic directory structure. (Fun fact: such a WIM will
654 crash Microsoft's software.)
657 Added new "extract" and "update" subcommands to wimlib-imagex, along
658 with associated APIs in the library. These commands are intended mainly
659 for Windows use but can be used on UNIX as well.
661 Many documentation improvements.
663 Fixed a bug in the Windows build where relative symbolic links were not
664 captured in reparse-point fixup mode.
666 Fixed a bug in the Windows build where file handles were left open to
667 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
669 Fixed a bug in the Windows build of wimlib-imagex where globbing
670 split-WIM parts could cause the program to crash.
672 Fixed a bug where the creation time of WIM images would be shown instead
673 of the last modification time.
675 With the Windows build it is now possible to restore a WIM containing
676 symbolic links as a non-Administrator; however you will receive warnings
677 about not being able to extract the symbolic links.
680 Capturing a WIM image should now be significantly faster in most cases
681 due to improved use of the operating system's cache and avoiding reading
682 files twice whenever possible.
684 The Windows build should now work on Windows XP.
686 The Windows build now supports capturing and restoring hidden,
687 compressed, sparse, and encrypted files.
689 The Windows build now supports capturing and applying WIM images from
690 filesystems other than NTFS (with some reduced functionality).
692 The Windows build now extracts short names correctly.
694 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
695 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
696 capture' and `wimlib-imagex apply'.
698 The performance of splitting and joining WIMs should be slightly
701 The LZX and XPRESS compression and decompression functions are now
702 exported from the library.
705 Improvements and bugfixes for the Windows build.
707 Added --strict-acls options.
709 Fixed the way that wimlib determines the order of images in the WIM.
712 Since wimlib can now be used on Windows, wimlib's implementation of
713 ImageX has been renamed to wimlib-imagex to avoid confusion with
714 Microsoft's implementation of ImageX, which would have the same file
715 name ("imagex.exe"). If you really don't like this you can pass the
716 --with-imagex-progname option to `configure' to choose a different name,
717 or even simply rename the binary yourself (but the former way will
718 configure the man pages to use the chosen name).
720 Various bugs fixed in the Windows build. Mainly to do with capturing
721 and restoring alternate data streams correctly in weird cases, and
722 requesting the correct privileges when opening files. Also added the
723 --noacls options to wimlib-imagex capture, append, and apply.
725 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
726 dynamically loaded, so this may make the library compatible with Windows
727 XP (however, there may still be other problems).
730 Added experimental support for native Windows builds. Binaries can be
731 downloaded from the SourceForge page.
733 --source-list option added to `imagex capture' and `imagex append'.
735 Better support for different character encodings.
738 Storing UNIX file owners, groups, and modes in WIM images is now
739 possible using `imagex capture' with the --unix-data flag.
741 Minor bug fixes and documentation fixes.
744 NTFS capture: Fixed capturing duplicate reparse points.
746 NTFS capture: Capture first unnamed stream if there are more than one
747 (print warning instead of error).
749 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
752 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
755 Update to work with ntfs-3g version 2013.1.13.
758 Fixed truncating file to shorter but non-zero length on read-write
761 Various code cleanups and minor documentation fixes.
764 LZX and XPRESS decompression have received some additional optimizations
765 and should now be even faster. (Although, they were already pretty
766 fast--- much faster than typical I/O speeds.)
768 Fixed a bug introduced in v1.2.1 that would cause a directory tree
769 containing hard links to be captured incorrectly in some cases.
772 By default, unmounting a read-write mounted WIM with 'imagex unmount
773 --commit' will now change the WIM in-place without needing to write the
774 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
777 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
778 for a response from the daemon servicing the mounted WIM. Instead,
779 every second 'imagex unmount' will check if the daemon is still alive,
780 and keep waiting if so, otherwise terminate with an error.
782 'imagex unmount --commit' on a read-write mounted WIM will now print
783 progress information regarding the writing of new or modified streams
784 the WIM, just like when capturing or appending a WIM.
786 A small change has been made to XPRESS compression and it should improve
787 the compression ratio slightly.
789 A change was made that may improve performance slightly when applying a
790 WIM image to a NTFS volume.
792 Microsoft has managed to introduce even more bugs into their software,
793 and now the WIMs for Windows 8 have incorrect (too low) reference counts
794 for some streams. This is unsafe because such streams can be removed
795 when they are in actuality still referenced in the WIM (perhaps by a
796 different image). wimlib will now work around this problem by fixing
797 the stream reference counts. This is only done when wimlib_delete_image() is
798 called ('imagex delete') or when wimlib_mount_image() is called with
799 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
800 requires reading the metadata for all images in the WIM, so this will
801 make these operations noticably slower on WIMs with multiple images.
803 Various other bugfixes.
806 Appending images to a WIM is now be done by default without re-building
807 the whole WIM. Use the --rebuild flag to get the old behavior (which
808 was to re-build the entire WIM when a new image is appended).
810 A new command `imagex optimize' is now available to manually re-build a
811 WIM that has wasted space due to repeated appends.
813 Progress information has been improved, and now arbitrary callback
814 functions can be used to show the progress of a WIM operation.
816 A possible bug with changing the bootable image of a WIM was fixed.
818 Some advisory locking is now done to prevent two processes from
819 modifying a WIM at the same time (but only in some cases). For example,
820 you cannot mount two images from a WIM read-write at the same time.
822 Some functions have been reorganized:
823 * wimlib_mount() renamed to wimlib_mount_image().
824 * wimlib_unmount() renamed to wimlib_unmount_image().
825 * wimlib_overwrite_xml_and_header() removed as
826 wimlib_overwrite() suffices now.
827 * wimlib_apply_image_to_ntfs_volume() removed as
828 wimlib_extract_image() suffices now.
829 * wimlib_add_image_from_ntfs_volume() removed as
830 * wimlib_add_image() suffices now.
832 Previously, the soname of libwim.so has been 0.0.0, despite many
833 interface changes. The soname is now updated to 1.0.0 and will now be
834 updated each release.
837 Resources will now be compressed using multiple threads by default.
838 (This applies to `imagex capture', `imagex append', and `imagex
841 Some performance improvements in mounted WIMs.
843 More progress information is shown when capturing a WIM.
846 Lots of minor fixes, code cleanups, and some documentation updates.
847 Nothing in particular is really noteworthy.
850 LZX and XPRESS compression improvements.
852 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
853 Link Bytes of the WIM.
856 Fixed bug when capturing NTFS file with multiple named data streams.
858 Internally, we are now using inode structures, even though these don't
859 appear literally in the WIM file. This simplifies some of the code
860 (mainly for WIM mounting) and likely fixed a few problems, although it
864 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
868 Enough changes to call it version 1.0.0!
870 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
871 to a NTFS volume, is now supported.
873 Hard links and symbolic links have much improved support. They are
874 supported for WIM capture, WIM application, and mounted WIMs (you can
875 even make them on read-write mounted WIMs).
877 Alternate data streams are now supported on mounted WIMs through an
878 xattr or a Windows-style stream interface. Also they are supported when
879 capturing a WIM from NTFS or applying a WIM to NTFS.
881 Split WIMs are better supported. You may now apply an image directly
882 from a split WIM, mount an image from a split WIM read-only, or export
883 an image from a split WIM.
885 Using a capture configuration file is now supported (but not fully yet).
887 SHA1 message digests are checked in more places, so we can make sure
888 applied and captured data is correct.
890 Man pages have been updated and consolidated.
893 Fixed segfault when unmounting read-only WIM.
896 Support for joining and splitting WIMs.
897 Also, security data is now preserved by default.
900 Can now build with older gcc and system headers, like on CentOS 5.
903 Fixed bug that made it impossible to overwrite files in read-write
907 Write byte-order mark before WIM XML data. (imagex.exe requires this to
